I "implemented" your code into cpuminer on an EC2 yesterday and can confirm the 220kh/s. Very nice! 
Thanks for your work on this and for sharing.  Very .

Although it seems to slow down over time but IIRC you mentioned that in the readme. After a restart of the miner it's running normal again.

Now if only cryptocurrencies all around wouldn't be crashing like no tomorrow right now... 

Yah, MtSux is slowly(?) getting worse than paypal when it comes to extending your limits / becoming trusted.

Thank you, all I wanted to hear.

A pool can only calculate your hashrate through your actually submitted shares/time.
So it could vary quite a bit at times... should be normal as long as your payout is what you'd expect (or accepted shares).

CFLAGS is used to pass arguments to the compiler. In this case "-O2" for optimization (enables various optimization flags) of the generated code, "-Wall" enables various warning flags and "-march=" selects for which processor architecture you'd like to compile, "native" determines the processor type of the compiling machine.

You can find most flags explained i.e. here.

Heh, interesting (obviously I never had an Avalon in my hands or did a lot of research about 'em), very good to know. Thanks for sharing ckolivas.

LUL... yeah, I saw the option but is it even possible to "circumvent" the hacked up tplink board they use (are the Avalon blades connected via USB)? But I too think a RPi should be more than sufficient, although Avalon added more RAM and stuff to the tplink board. I believe I even read that Bitmine.ch is planning to replace the tplink board with a RPi in their clones at a later time.

Compiled it on my Pi and it looks like as if it does perform much better with lesser HW errors still on diff 1 (check my previous post). Also, no need for additional options just like with 3.2.0. Thanks ckolivas and kano for the fast cgminer updates. Here's an addition to my previous post to get my test build to 3.2.1. Stop cgminer and do this:

Man, bei diesem China-Ramsch hätte ich Angst das es mit die Bude abfackelt, besonders wenn ich nochn stärkeres Netzteil dranhänge.

Well for what it's worth, here are my results of building and testing cgminer 3.2.0 on a Raspberry Pi running MinePeon-2013-05-25 (all in all pretty straightforward). Please consider, as a test, I did all this as root which might not be the best choice if you want to "update" your Minepeon system with it later on.

Imagine I'm logged in through ssh, I did a system upgrade beforehand.

Then I got the sources from the repo and built cgminer (btw, you need at least "--enable-icarus" for the USB Block Erupter to be supported). It suggests a little different compile flags in the README, you might consider using those.

This should compile cgminer without errors obviously. Don't forget to stop any mining tool that might be running.

Optional but lets start cgminer in a screen window, always nice.

Then I just ran cgminer without any special options.

It threw some "comms error" msgs but after a sec all miners showed up and started hashing.  

Here are my stats with a diff of 1 at start and 2 hours later (2 Lancelots and 5 USB Erupter). I still have to investigate the exceptionally high HW errors on 2 of the USB Erupters (But I got them too using the "build-in" versions of cgminer and bfgminer when I started hashing with these babys).





(seems cgminer sometimes reports wrong speeds like on BLT 1 in the 2nd pic, but that is sporadic and it is correct again after a short while, well here at least)

So all in all cgminer performs pretty nicely on my Pi. Thanks to the devs for all the effort they put into it!

IIRC the pictures on ebay were stolen from here.

Hm, die sind auch nett. Genauso wie die Anker Teile bei dem 42 Miner Setup (so neat btw <3).
Weißt Du ob die mit dem Pi und z.B. Minepeon gut laufen?

EDIT: Damn, Pi's mögen zumindest keine Anker scheinbar.

Habe diesen hier... hat wenigstens ein 3.5A Netzteil und versorgt 5 USB ASICs, 1 Lancelot (fällt nicht ins Gewicht) und einen USB Ventilator aber nicht den Pi (weil Ports voll) ganz gut. Er steht mit auf dieser Liste: http://elinux.org/RPi_VerifiedPeripherals#Working_USB_Hubs

Weiss nicht ob dir das hilft.

Habs noch nicht selbst getestet mit 3.2.0 aber werde es vermutlich heute abend auf einem Raspberry Pi.

Hier ist der Post von kano bzgl. Änderungen in 3.2.0:
https://bitcointalk.org/index.php?topic=220450.msg2324764#msg2324764

Laut diesem sind keine seriellen Treiber für Win mehr nötig (deinstallieren!) sondern läuft über zadig und ansonsten sollte cgminer 3.2.0 alle Devices selbst erkennen (kein -S mehr).

EDIT: Sorry, immer hilfreich wenn man den ganzen thread liest... 3.2.0 scheint wohl doch noch ein paar kleine Probleme zu haben. Werds trotzdem mal (zwar unter Linux) testen.

Got my 5 Erupter yesterday.

Here's my setup. In hindsight I do like the Anker USB3.0 hub setup (the 50 ASICs one ) quite a bit and maybe I should have gone that way... Wouldn't be so cluttered but oh well.

Thanks a bunch to yxt for organizing this group-buy. Has been a real pleasure, kudos! 

Btw, is this the reason group-buys won't be necessary in the future you were talking about by any chance?

No, you just have been patronizing me at what point I should have asked my questions.

Makes you think doesn't it, coming from the guy who even took a visit to bitmine.ch's facilities to prove exactly that it is not and with their full refund gurantee how can there be any risk at all? Or did I miss something?

I just wondered how they plan on fulfilling 100+ more orders without an additional 40k+ of ASICs and hence my question (still unanswered and I wonder why nobody else of the batch #2 customers has asked this yet).

But yes, I have been quite the douche yesterday and would like to apologize for spewing nastiness (did I really make a "dick" reference? Oh lord...).
Especially to one4many and bitmine.ch, of course I appreciate the trip you made and the report. Normally I don't fly off the handle so easily but I was a liiittle stressed out yesterday and pretty on edge to put it this way.

All I can say is, my apologies again to all (which I guess you won't see since I made your ignore list).

And what difference please would that have made in your opinion? Did they loose their fingers or online access since then? What if I just saw this thread, had only a "few minutes" until batch #2 might be sold out and wanted to get in? Just because I preordered and intend to follow through (read: pay for it) I still do have some questions which would ease my mind and simply would like to get answered when I spend $7000 out front on a product.

And jeeez, get off your high horse, just because you rubbed dicks with the 2 guys doesn't mean you can command or propose when a customer can or should have asked questions about a product. Are you even a customer with them?

Sorry for my tone but I'm getting a little pissed now defending why, when or what I ask... to which I still haven't gotten an answer to.

I am in the same timezone as them and posted my questions the first time shortly after the preorder start.
Also, when I schedule the start of a preorder, especially for a high profile and sensitive item like this, I would factor in some time for customer questions and feedback.

Start was at 8 PM, I doubt they went to bed that early.

In fact they should be right in their office hours right now and none of 'em is even online...
An answer to the question about EUR payments would be really nice because I need to wire the funds very soon now.

Yeah, more like this I could imagine.

Lol, don't say something like that, feeling raped more and more.

Well, I guess starting a new batch of preorders and going offline/silent shortly after with open questions from customers might be an answer in itself...

Let me post them again...

You brought in 100,000 sFR and bought 10k Avalon ASICs which would cover preorder batch #1. So, did you bring in more money to order more ICs (at least 40k ASICs by my calcs) to cover batch #2 (which suddenly has over 3x more stock than the 1st)? Without touching preorder money so you can refund customers?

Second, can we pay the wiretransfer in EUR?

Don't get me wrong, I believe in you (*bites tongue*) and plan on wiring the money today in any case but would feel much more confident if there where more transparency and you would answer these questions.

Hey!
I see, thanks for clarifying that.
Just one more question if I may. Did you order more Avalon ASIC IC's because with 10k you can only cover preorder batch #1 if I count correctly.

Don't know if I should feel lucky or raped but I preordered one. HAH

Hmmm, can you elaborate on "All sales are final"? I read this exact same wording "somewhere"...
Didn't you say you'd guarantee a refund whenever a customer requests one?

And would it be possible to pay the wiretransfer in EUR?
